About Sound Levels
Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.

Hazardous Location Spark-Resistant Blowers
These blowers have an explosion-proof motor that is UL listed for hazardous locations. They also have an aluminum housing for spark resistance. These blowers install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Portable Fume Exhausters
In addition to using the handle to carry these exhausters, you can mount them to a wall, bench, or floor. They remove fumes, vapors, and fine dust particles from your space. They are commonly used in welding, soldering, and other operations that create fumes. All have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments. They have a flexible hose with nozzle to capture fumes at the source and rubber pads on the base to reduce vibration.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
Single-duct kits (sold separately) include a hose, a nozzle, and two clamps to replace existing components.
